Helping a relative with will in Texas. He wants to leave his gun collection to a grandson that is now is in a federal prison. He is in on a drug charge with a weapon. Will he ever be allowed to own a gun? Thanks
If he is in prison on a "charge", then if he is found not guilty, it may not affect his ability to own firearms.
If he's already been convicted and is serving a sentence, it would depend on if the maximum possible penalty exceeds a year.
Generally the Feds don't bring charges they can't sustain, and I don't think they bother with misdemeanor charges.
In short, my GUESS is that he is, or will be, prohibited from owning firearms.
